Item Details

  • This analytical series of high-purity brass single-stage regulators is recommended for non-corrosive analytical and process applications where precise pressure control is not required. The check valve cylinder connection prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. Machined from brass bar stock, this regulator body has minimal internal volume - there are no large cavities and pockets associated with forged-body regulators. These models feature encapsulated filter assemblies to protect the valve seat from contamination, extending regulator service life while also reducing velocity of gas when opening high-pressure cylinder valves. An automatic reseating relief valve protects regulator components from over pressurization. Chrome-plating makes the appearance last through many years of service.

Features

  • Check Valve Cylinder Connections: Prevents air and contaminants from entering process stream during cylinder change out.
  • Stainless Steel Diaphragms: Eliminates outgassing associated with elastomeric diaphragms.
  • Bar Stock Body: For low internal volume.
  • Encapsulated Filter Seat Assembly: For added gas stream purity and extended service life.
  • Chrome Nickel-Plated Brass Body: Provides long-lasting good looks - will not tarnish.
  • Mounting: Front panel mount bonnet and (2) #10-32 holes for rear mounting.
